I don't know if it's the moustache, the cool dungarees, or the plumbing proficiency, but I love Mario. He is a beautiful and good man. My favourite Mario, however, is Tanooki Mario, or Raccoon Mario (they are slightly different variations on a theme - the badge shown above is Raccoon Mario - but they're close enough that I'm lumping them together as my Mario form of choice).
Mario was impressive enough already, but in these forms he can glide majestically through the sky, and into my heart. Please offer your love, respect, and admiration to Mario. That is all.
